Title: Metal support pin for refractories - is welded to wall of water pipe to allow max. hardening or sintering
Inventor: ABRAHAM UWE
IPC: F16L59/14
Filed: 1975-09-27
Abstract: The metal support pin (26) for refractories is welded to the wall of a water pipe (1) and shaped to constrict flow of heat from the point of attachment to the free end. The support pin may have a narrower cross-section in the region between the point of attachment and the free end, pref. a hyperbolic constriction located approx. centrally. It may include between the point of attachment and free end a layer (6) of poorer heat conductivity compared with the remaining regions of the support pin. Cooling of the support pins at their free ends by the medium in the pipe cannot occur or is greatly reduced, so that the outer ends of the support pins remain hot and accordingly cannot cool the immediately surrounding refractory material (4), thus allowing max. hardening or sintering of the refractory material.

Title: Extruded sausage closure device - has shear arm pairs with overlapping tips and specified turning radius of cutouts
Inventor: NIEDECKER HERBERT DIPL ING
IPC: A22C11/10
Filed: 1975-11-07
Abstract: Sections of packages are divided off from a continuous filled hose (single sausages from a continuous tubular skin filled with sausage meat) by two pairs of shear arms. These arms form a reception space between them and overlap with their tips even when fully open, where they are guided by U-rails. The deepest part of the V-cutout in the arms turns at a smaller radius from the shear pivot than the centre of the extruder nozzle. This avoids any damage to the sausage skin, especially when the tubular skin has a dia. >55 mm. The design is simple and no excessively long paths and times of closure need be applied.

Title: Electrical conducting compsn. - based on copper powder and a phenol resin generating formaldehyde on hardening
Inventor: REILLY JOHN J
IPC: C08K9/02
Filed: 1976-04-06
Abstract: The compsns. contain an intimate mixt. of (a) a relatively H2O free prepolymer phenol resin with low viscosity, contg. H. CHO which can be set free within the compsn., and (b) 50-90 wt. % of a particle form metal filler from oxide coated Cu and/or oxide coated Cu alloys. In an example, 5 pts. wt. of phenol resin (trimethylolallyl phenol), 5 pts. wt. of epoxide resin (DER 736 Dow Chemical Co.) and 90 pts. wt. of Cu powder (325 mesh) were mixed and hardened at 150-200 degrees C for 1/2-1 hour. H. CHO set free in the hardening reduces any Cu oxide film present on the Cu particle to result in an electrically conducting compsn. The oxide film in the Cu used is removed by free H. CHO released on hardening. The solid resin type compsns. have a conductivity similar to those in which Ag is used and are more economic. Since a catalyst is not essential, or if used is not in excess, the compsns, have a long pot-life i.e. >=1 year at room temp. The prods. are used for e.g. resistance elements, the repair of printed circuits, conductors on glass for e.g. de-icers, conducting adhesives for electronic equipment.

Title: Elastic insulating materials - of closed cell foam particles in binder with additive of specified particle size to give greater moisture diffusion in binder than in foam
Inventor: ROTH HANS JOACHIM
IPC: C04B38/08
Filed: 1976-10-01
Abstract: Elastic insulating materials are based on (a) a binder and (b) particles of a closed cell foam with a negative sieve line compsn. of about 1/3 to 1/15 mm. Each particle fraction in the additive consists of overfoamed particles, foamed to just below bursting point. The binder between the foamed particles has a resistance to diffusion which is lower than that of the particles by a factor of u = 5. The binder used may be any known organic or inorganic binder such as portland cement, lime etc. The foamed particles are e.g. of foamed polystyrene and additives such as silicates with a particle size of 0/1 mm or hydrophilic silicic acid may be incorporated to improve the packing between the foamed particles. The foamed particles may be in the form of pearls, milled foam, etc. The binder may contain modifiers such as plastics dispersions, anionic melamine-formaldehyde condensates, starch ethers, etc. The particle size distribution of the foamed particles and additives is designed to give greater diffusion of water vapour in the binder lattice than in the foam particles. the materials retain improved thermal insulation properties for extended periods of service.
